Biological Activity

Galanthamine hydrobromide is a long-acting, centrally active acetylcholinesterase inhibitor (IC₅₀ = 410 nM) and allosteric potentiator at neuronal nicotinic ACh receptors. Prevents β-amyloid-induced apoptosis in SH-SY5Y and bovine chromaffin cells. Long-term administration reduces amyloid precursor protein deposition and neurodegeneration in a mouse model of Alzheimer's disease.

Preparing Stock Solutions

The following data is based on the product molecular weight 368.27.

Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Concentration / Solvent Volume / Mass	1 mg	5 mg	10 mg
0.2 mM	13.58 mL	67.88 mL	135.77 mL
1 mM	2.72 mL	13.58 mL	27.15 mL
2 mM	1.36 mL	6.79 mL	13.58 mL
10 mM	0.27 mL	1.36 mL	2.72 mL
